I. Aix

1. view the number of CPUs:

(1) Since aix5.3, smtctl introduces the SMT (simultaneousmulti-threading) function for power5 machines. It allows two processing threads to run on the same processor, for an operating system, a physical processor logically becomes two processing units (logical processor ). SMT function enabled: the number of logical CPUs is twice the number of physical CPUs. SMT function disabled: the number of logical CPUs is equal to the number of physical CPUs.

(2) bindprocessor-Q to view the number of logical CPUs

(3) Run vmstat to view the number of logical CPUs

(4) view the number of physical CPUs in prtconf

(5) lsdev-CC processor to view the number of physical CPUs

(6) lscfg | grep proc lsattr-El proc0 lscfg | grep mem lsattr-El mem0

2. View mem size

(1) lsdev-c | grep mem
(2) lsattr-El mem0 lsattr-e-l sys0-A realmem

3. View virtual memory

LSPs-

4. View System digits

Hardware: bootinfo-y

Operating System: bootinfo-K

2. HP-UNIX

1. view the number of CPUs

(1) echo runningprocs/d | ADB-k/STAND/vmunix/dev/MEM
(2) SAR-M 1 1 | awk 'end {print NR-5 }'
(3) ioscan-fnk | grep processor | WC-l

(4) machinfo

(5) lscfg | grep proc lsattr-El proc0 lscfg | grep mem lsattr-El mem0

(6) psrinfo-v | grep "Status of processor" | WC-l

(7) ioscan-fncprocessor

2. view memory

(1) dmesg | grep-I physical

(2) SAM

(3) Non-root users can use: CAT/var/adm/syslog. log | grep physical

3. View System digits

Print_manifest

Iii. Linux

1. view the number of CPUs

(1) CAT/proc/cpuinfo processor COUNT = number of logical CPUs; number of unique physical IDs = number of physical CPUs

2. view memory

(1) CAT/proc/meminfo
(2) free
(3) Top

3. View System digits

Getconf long_bit
